[Ureteral obstruction caused by aneurysm of iliac artery]
Insights
A common iliac artery aneurysm caused right ureteral obstruction. Surgical repair involved an aorto-iliac graft bypass and ureterolysis, successfully treating the hydronephrosis.
Area of Science:
- Vascular Surgery
- Urology
Background:
- Iliac artery aneurysms can cause extrinsic compression of the ureter.
- Ureteral obstruction due to vascular anomalies presents diagnostic and therapeutic challenges.
Abstract:
A 76-year-old man was referred to our hospital because of right hydronephrosis. A retrograde pyelogram showed obstruction of the right ureter at the level where it was crossed by the common iliac artery. A computerized tomography scan demonstrated an encased right ureter and aneurysm of right common iliac artery. Arteriography revealed aneurysm of right common iliac artery. An aorto-iliac graft bypass and ureterolysis were performed with intra-peritoneal displacement of the right ureter. The diagnostic procedures and treatment modalities for ureteral obstruction caused by aneurysm are discussed.
